DEVICE FOR LEVELING'BOILERS OF ROAD-ENGINES.

SPECIFICATION forming part of Letters Patent No. 264,500, dated September 19, 1882. Application filed June 28, 1882. (No model.)

To all whom it may concern:

Be it known that we, T. FRANK WILSON and ALBERT L, WILsON. citizens of the United States, residing at Gorham, in the county of Ontario and State ofNewYork, haveinvented certain new and useful Improvements in Devices for Leveling Engine-Boilers, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This invention relates to the broad idea of keeping the boiler of a traction orother engine level in going up or down inclines or hills, to prevent the water in the boiler flowing to one end or the other, to the great danger of of explosion, or putting the fires out, and other disadvantages.

The invention consists in keeping boilers of movable engines level, when moving on uneven roads, by the simple means shown and described hereinafter, or equivalent devices.

In the drawings, Figure l is a side elevation, and Fig. 2 afront end elevation, of a traction-engine.

A represents theboiler, and B the rear and fire-box end, of a traction-engine with wheels (J D. The moving parts of the engine are not shown, as being unnecessary to the present description and invention. e

As an illustration of the working of this invention we proceed to describe the parts shown, whereby we accomplish the object stated.

To the center of the axle a of the front wheels is pivoted a horizontal metal bar, 1), running back below and under the boiler A for a short distance, and made longer or shorter, according to the greater or less depression required of the boiler and the height from the ground. A short vertical post, 0, is fastened to the under side of the boiler, a little back of the front wheels, whose lower point sets in a socket in the horizontal bar I), and is there p loosely attached, so as to allow an up-anddown play to the bar I). To the rear end of this bar I) is fastened a chain, d, or its equivalent, the two ends attached to adrum or rod, 0, running under and across the boiler-bottom. (See Fig. 2.) This drum or rod eworks in and is held by hangers f f, attached to the boilersides or its frame-Work, one end of drum having a toothed wheel, 9, meshing into a worm, h, on the end ofa long crank-rod, It, held in suitable rests, and running to the back end of engine, to be operated by the engineer, who by merely turning the crank-rod It by its handle makes the Worm operate the drum and winds up the chain d, which draws up the end of the bar I) at an incline, and thereby raises the front end of the boiler. This levels it going down inclines or hills, and by unwinding the chain when the engine starts up an incline the front of the boiler is depressed, thereby leveling it. -Of course the length of post 0 and bar 12 and height of the boiler from the ground will all be properly regulated in building, so as to get the proper pitch.

I claim In combination with the boiler A ofa movable engine,,the post 0, horizontal bar b, attached to front axle, ct, its-rear end raised and lowered by chain 01, drum or rod 6, toothed wheel 9, and worm It on crank-rod It, all substantially as and for the purpose specified.

In testimony whereofwe affix our signatures in presence of two witnesses.
